Resumen

The genus Puya (Bromeliaceae) is highly endemic in Peru. By comparing the morphological characters of several populations located in southern Peru, we report a new species providing data on their ecology, distribution and conservation status. Puya pereae sp. nov. is characterised by retrorse spines towards the base of the leaves, paniculate inflorescence with branches of up to 26 flowers, primary bract margins entire to irregularly denticulate, floral bracts smaller than the length of the sepals, and sepals with tomentose indumentum. The populations studied were previously confused with P. densiflora, an eastern Andean species with antrorse spines towards the base of the leaves and cylindrical inflorescence. In addition, the characters of P. pereae are discussed in relation to those of other related species, and the localities of the material studied are mapped.
